Manganese is a chemical element, designated by the symbol Mn. It has the atomic number 25. It is found as a free element in nature (often in combination with iron), and in many minerals. Manganese is a metal with important industrial metal alloy uses, particularly in stainless steels.
Historically, manganese is named for various black minerals (such as pyrolusite) from the same region of Magnesia in Greece which gave names to similar-sounding magnesium, Mg, and magnetite, an ore of the element iron, Fe. By the mid-18th century, Swedish chemist Carl Wilhelm Scheelehad used pyrolusite to produce chlorine. Scheele and others were aware that pyrolusite (now known to be manganese dioxide) contained a new element, but they were not able to isolate it. Johan Gottlieb Gahn was the first to isolate an impure sample of manganese metal in 1774, byreducing the dioxide with carbon.
Manganese phosphating is used as a treatment for rust and corrosion prevention on steel. Depending on their oxidation state, manganese ionshave various colors and are used industrially as pigments. The permanganates of alkali and alkaline earth metals are powerful oxidizers. Manganese dioxide is used as the cathode (electron acceptor) material in zinc-carbon and alkaline batteries.
In biology, manganese(II) ions function as cofactors for a large variety of enzymes with many functions.[1] Manganese enzymes are particularly essential in detoxification of superoxide free radicals in organisms that must deal with elemental oxygen. Manganese also functions in the oxygen-evolving complex of photosynthetic plants. The element is a required trace mineral for all known living organisms. In larger amounts, and apparently with far greater activity by inhalation, it can cause a poisoning syndrome in mammals, with neurological damage which is sometimes irreversible.

1. The purity of electrolytic manganese is very high. Its function is to increase the hardness of the composite metal material. Manganese can improve the strength, toughness, wear and corrosion resistance of certain alloys.
2. Manganese is an indispensable additive in the smelting industry. After electrolytic manganese is processed into powder, it is the main raw material for the production of manganese trioxide.
Manganese Metal Lump is an additive for steel making and Non-steel Alloys. It can go deep inside of liquid Steel to achieve the final manganese concentration required in steel.
Electrolytic Manganese Metal Flakes has been widely used in production of steel and stainless steel and Non-Steel alloys. It plays important role in desulfurization deoxidation and alloying. Manganese can increase strength tenacity, abrasive resistance, and corrosion resistance of steel.
Electrolytic manganese is the elemental metal precipitated by acid leaching of manganese oreã??
Applications:
With high purity,low impurities,Electrolytic Manganese Metal Flakes are widely used in Iron and steel smelting, non-ferrous metallurgy, electronic technology, chemical industry, environmental protection, food hygiene, electrode industry, aerospace industry and other fields.
Electrolytical manganese mainly used as an additive,to increase the strength, toughness, abrasion resistance and corrosion resistance of alloys in the field of steel smelting, manganese copper alloy,manganese aluminum alloy,200 series stainless steel.
